Android Auto not working on Cadillac CT4

If Android Auto does not start on your CT4 when you plug in the USB cable and there is no Android Auto icon in the list of apps in the infotainment system, it can be due to a number of reasons:

  • Android Auto is disabled in the infotainment system settings of your CT4.
  • Android Auto is not installed on your phone, make sure its installed and have necessary permissions.
  • The USB data cable you’re using is defective or off-brand. Try a different cable, preferably original cable.
  • The connected USB port on your CT4 does not support Android Auto. Try other USB ports.
  • A software glitch is responsible for the Android Auto problem. Try resetting the CT4’s infotainment system to its factory settings. Also, delete data and cache for Android Auto on your phone by going to Settings> Apps > Android Auto > Storage.

If you still can’t connect Android Auto in your CT4, then you should get your vehicle checked by an authorized Cadillac dealer.

Using Google Assistant on Cadillac CT4

Google Assistant is an artificial intelligence–powered voice recognition feature by Google that helps you to concentrate on the road while driving your CT4 as you can control the functions of your Android device with voice commands.

The virtual assistant allows you to place phone calls, listen to and send text messages, play music, get directions and use other functions of your Android phone hands-free. You can even ask Google Assistant for current weather conditions, stock prices or upcoming events on your calendar.

To access Google Assistant, press and hold the talk button on the steering wheel of your CT4 until you hear an audible alert.

Which CT4 models support Android Auto?

2020 and later model year Cadillac CT4 vehicles are compatible with Android Auto.

Using Waze navigation on Cadillac CT4 with Android Auto

Waze is based on a combination of the Android Location Service and real-time information from the 100 million user database. It is one of the best apps in the world when it comes to including construction work and traffic in the route suggestions. Waze can also provide updated information on accidents and unexpected delays. The app is fully compatible with Android Auto. Just download Waze app from Google Play Store on your phone and press its icon in Android Auto app in your CT4’s infotainment screen.

Using Google Maps on Cadillac CT4 with Android Auto

There’s no list of the best Android car apps without including the top dog in sat-nav apps, Google Maps. Maps is an important part of the Android ecosystem and will likely be the app that you use the most when you’re driving your CT4. For many people, choosing between Waze and Google Maps is a matter of personal preference. We think: Both are great. You do not need to download Google Maps app as its a built-in feature in Android devices.

Using Spotify on CT4

You can use Spotify to stream music on your CT4. Just install the Spotify app from Google Play Store and its icon will appear in the infotainment display when Android Auto is active.

You can use voice commands to play music hands-free on Spotify with Google Assistant. Just add “on Spotify” at the end so that Google Assistant knows which service you’re referring to (e.g. “Hey Google, play my ‘Your Mix of the Week’ playlist on Spotify”).

Google Assistant can play songs, artists, albums, playlists, podcasts, and more. You can also “like” music, ask what’s playing, and control playback (e.g. volume, skip song, play / pause).

Not all apps are compatible with Android Auto

If you think you can use all your Android apps in your Cadillac CT4 with Android Auto, then you’re wrong. The selection of compatible applications is limited, and you have to live with restrictions, especially with messenger apps. SMS messages and WhatsApp can be controlled almost exclusively via Google Assistant. That means you cannot see your message history, but only have new messages read out to you or even dictate messages yourself.

The following apps can be used with Android Auto on your CT4, among others: Phone, Whatsapp, Messages, Facebook Messenger, Skype, Telegram, Calendar, News, Pandora, Spotify, iHeartRadio, Audible, Amazon Music, YouTube Music, Waze and TomTom GO.
